strument must currently be on the specified function in order for ONCE to be effective. Using
ONCE while on any other function results in an error.
The autorange command (:RANGe:AUTO) is coupled to the command that manually selects the
measurement range (:RANGe <n>). When autorange is enabled, the parameter value for
:RANGe <n> changes to the automatically selected range value. Thus, when autorange is dis-
abled, the instrument remains at the automatically selected range. When a valid :RANGe <n>
command is sent, autoranging disables.
When using auto range, upper and lower range limits can be established to keep the instrument
from autoranging to ranges that are not going to be used. (see :AUTO: ULIMit and :AU-
TO:LLIMit commands).
NOTE
Allow sufficient time for settling when autoranging over multiple ranges or down to the lower
current ranges, or erroneous readings may occur.
